Pegasus is a constellation in the northern sky, named after the winged horse Pegasus in Greek mythology. It was one of the 48 constellations listed by the 2nd-century astronomer Ptolemy , and is one of the 88 constellations recognised today.
NGC 7735 is an elliptical galaxy in the constellation of Pegasus. Its velocity with respect to the cosmic microwave background is 9249 ± 36 km/s, which corresponds to a Hubble distance of 136.41 ± 9.57 Mpc (∼445 million light-years). [1] It was discovered by British astronomer John Herschel on 5 September 1828. [2]
The equatorial region of the celestial sphere's western hemisphere includes 13 navigational stars from Gienah in the constellation Corvus to Markab in Pegasus. It also includes stars from the constellations Virgo, Bootes, Libra, Corona Borealis, Scorpio, Ophiuchus, Sagittarius, and Aquila.
NGC 7625, or Arp 212, is a peculiar galaxy in the constellation of Pegasus.It was discovered on October 15, 1784, by William Herschel. [8] In his New General Catalogue (1888), J. L. E. Dreyer described it as pretty bright, considerably small, round, with a suddenly much brighter middle. [9]
NGC 7363 is a barred spiral galaxy in the constellation of Pegasus. Its velocity with respect to the cosmic microwave background is 6393 ± 24 km/s, which corresponds to a Hubble distance of 94.29 ± 6.61 Mpc (∼308 million light-years). [1] It was discovered by German astronomer Heinrich d'Arrest on 27 August 1865. [2]
NGC 7678 is an intermediate spiral galaxy located in the constellation Pegasus.It is located at a distance of about 130 million light years from Earth, which, given its apparent dimensions, means that NGC 7678 is about 95,000 light years across.
HD 209458 is a star with an orbiting exoplanet in the constellation Pegasus. It has an apparent visual magnitude of 7.65 [2] and an absolute magnitude of 4.28. [5] Because it is located at a distance of 157 light-years (48 parsecs) from the Sun as measured via parallax, it is not visible to the unaided eye.
Messier 15 or M15 (also designated NGC 7078 and sometimes known as the Great Pegasus Cluster) is a globular cluster in the constellation Pegasus. It was discovered by Jean-Dominique Maraldi in 1746 and included in Charles Messier 's catalogue of comet -like objects in 1764.
